I encountered a blank display (all white) on my second monitor when trying to
view a presentation file and large settings for my graphics display resolutions
(Mon.1:1152x864,Mon.2:1280x1024)
Secondary display would not show any slide. Primary monitor did show the
presentation. Could not temporarily use two monitors with OOo. (Worked fine with
      with PowerPoint)

 This issue is similar to Issue 70721, but I didn't find a more closer issue to
my problem, and was expecting it to work in a newer release.  I apologize if
there is another issue that I didn't find, being just new to the program and the
project.
 After testing my system, the following settings (M1=Monitor 1, M2=Monitor 2)
and results are:
A. Program on primary monitor, Presentation Mon. on Monitor 2
  a. M1:1024x768, M2: 1152x864: OOo shows: Yes
  b. M1:800x600, M2: 1152x864: OOo shows: Yes
  c. M1:1152x864, M2: 1152x864: OOo shows: No
  d. M1: 1024x768, M2: 1280x1024: OOo shows: No
  e. M1: 1152x864, M2: 1280x1024: OOo shows: No

Switching the program and monitor settings, I get different results:
B. Program on secondary monitor, Presentation Mon. on Monitor 1
  a. M1: 1152x864, M2: 1024x768: OOo shows: Yes
  b. M1:1152x864, M2: 800x600: OOo shows: Yes
  c. M1:1152x864, M2: 1152x864: OOo shows: Yes
  d. M1:1280x1024, M2:1024x768: OOo shows: Yes
  e. M1:1280x1024, M2: 1152x864: OOo shows: Yes

I tested 11 different monitor settings, 6 moderate, and 5 higher resolutions.  I
thought the issue at hand could be surpassing my video card capabilities.
My desktop has a ATI Radeon 7000 with 32MB memory; running 760MB RAM. However,
further testing in PowerPoint (v.2000) resulted in success in all 5 higher
resolution settings for two monitors on Monitor 2.  OpenOffice did show the
presentation on Monitor 2 for the six moderate display settings, then passed 2
of 5 higher resolution settings, as shown above.  When I switched the display to
Monitor 1, and tested opposites, OpenOffice showed the presentation at 5 of 5
higher resolutions.
 This occurred only in Impress Presentation, OOo.3, with three different files,
opened with two imported .ppt files, and a new .odp file.
(Originally I thought there was compatibility issues and resaved/reopened with
PowerPoint v.2000.)


Documenation:
Preliminary: Opened a working presentation program (.ppt or .odp)
Step A: Place Program in Monitor 1. Verified Display output to second monitor:
SlideShow|Slide Show Settings; Presentation Monitor: Monitor 2
  1. Change display resolution settings: Windows Display Properties\Settings
Tab, etc.
  2. Select slide, Start show (Slide Show button or View|Slide Show or F5),
Advance slide, Esc.
  3. Notate the visibility of the presentation.
  4. Repeat steps A.1. thru A.3. for different values of monitor settings.

Step B: Place Program in Monitor 2. Verified display outupt to primary monitor:
SlideShow|Slide Show Settings; Presentation Monitor: Monitor 1
Similarly, 
  1. Change display resolution settings: Windows Display Properties\Settings
Tab, etc.
  2. Select slide, Start show (Slide Show button or View|Slide Show or F5),
Advance slide, Esc.
  3. Notate the visibility of the presentation.
  4. Repeat steps B.1. thru B.3. for different values of monitor settings.

I tested eleven different settings, in order of combined resolution video
demand, which resulted in Steps A (Secondary monitor) the Program showed the
presentation for the first 8 of 11 tests. Steps B (Primary monitor), the Program
showed the presentation for all 11 of the display tests.
 I am guessing there may be "cap" to displaying a presentation on the second
monitor (Monitor 2). However, there may be a problem with my video card, and in
order to overcome the issue, I can change my display resolution in one or the
other monitor.
